SIGHT-PIECE.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed May 13, 1904- Serial No. 207,779-

To all whom, it may concern:

Be it known that we, JOHN Y. BASSELL and FRED C. BLENKNER, citizens ofthe United States, residing at Columbus, in the county of Franklin andState of Ohio, have invented a certain new and useful Improvement inSight- Pieces, of which the following is aspecification.

Our invention relates to a new and useful improvement in gun-sightpieces.

The object of the invention is to provide a superior sight-piece inwhich the sight-center is supported within a ring which when used inconnection with a globeso concentrates the aim as to insure greataccuracy.

Finally, the object of the invention is to provide a device of thecharacter described that will be strong, durable, and eflicient and onewhich will be simple and comparatively inexpensive to make.

With the above and other objects in view the invention consists of thenovel details of construction and operation, a preferable embodiment ofwhich is described in the specification and illustrated in the drawings,wherein Y Figure 1 is a front elevation of one of the sightpieces. Fig.2 is a front elevation of a modified form having the cross-line center.Fig. 3 is a front elevation of still another form employing thecross-center. Fig. 4 is a front elevation of a globe, showing the sight-Fig. 1 supported therein,- and Fig. 5 is a side elevation of one of thesightpieces.

It is to be understood that the essential feature of the inventionresides in a ring 1, which is suitably supported by any means, althoughwe prefer to use a stem 2. Various forms of centers may be supportedwithin the ring. In Fig. 1 we have shown what is commonly known as theball-center.3, and it Will be readily apparent that the centering of theaim on the ball 3 is greatly facilitated by the ring I, which whensupported in the globe 4 readily attracts the eye and enables the gunnerto easily get a line on the bullseye of the target;

In Fig. 2 we have shown cross-lines 5, sn ported Within the ring 1,which is preferab e in some instances, and in Fig. 3 we have shown at 6a cross-center supported within the ring 1, by the addition of whichring the value of the center is greatly increased.

These sight-pieces may be formed with any suitable form of base by whichthey are supported in the globe, so that they may be readilyinterchanged, so that different forms of sight-pieces may be used forvarious kinds of shooting. It is within the scope of our invention toilluminate the sight-centers, so as to contrast them with thesurrounding parts; but the sight-center may be formed in any suitablemanner, according to the purpose for which it is employed.

It will be observed that by employing the ring 1 the same greatly aidsin aiming the arm, as where ringed targets are used the ring 1 willconform to the rings on the target and facilitate the alining of thecenter with the bulls-eye. .Thus a gunner is enabled to draw the finestbead, and the aim is concentrated from the ring to the sight-center andany slight deviation will be readily discernible.

e do not wish to limit ourselves to the exact details of constructionand operation herein set forth, as we may make various changes in thesame without departing from the spirit of our invention.

Having now fully described our invention, what we claim, and desire tosecure by Let ters Patent, is

1. A sight-piece adapted for use in conjunction with a adapted to bedisposed concentric with the globe-center, but having a smaller diameterthan the globe so as to provide a substantial space therebetween, and asight-center supported from the ring.

2. A sight-piece adapted for use in conjunction with a sight-cylindercomprising a ring adapted to be disposed within and concentric with thecylinder so as to provide an annularinterspace therebetween, and asightcenter supported within the ring.
